Sin & Punishment: Stage 1-2 & 1-3 (Normal)
4Saki, Airan, and Achi have made it inside Shinjuku Station and activated the elevator upward.
For Stage 1-2, more Volunteers to battle against. Shoot some pipes down to roll them over, but watch out for the rolling pipes, yourself.
After getting high enough with the elevator, another high-ranked Ruffian shows up: The Lizard Seemer. Watch out for his deadly chain whip, and try to strike him with the sword when he gets up close as much as you can.
Speeding up the elevator, there will be more Ruffians to face before the trio reaches the top.
----
They reach a transport off the station, but Saki was slowed down by another Ruffian boss, simply called Radan. Achi tried to knock it down with the transport, but it came back up for more to deal with Saki, all while a new girl watched.
For this boss fight, you can move Saki back and forth in a sideways position. Dodge Radan's attacks and get as much damage on him as soon as possible, including knocking him off the ledge again.
----
After defeating Radan, it turns out that this new hostile girl is Kachua, the Volunteers' Captain and the same one from the game's opening talking to someone else telepathically. She now wanted to take on Saki itself through the power of the blood that was given to him by that other man...
Kachua will use her power to toss a bunch of soldiers and vehicles at you. You gotta take them down first before you can fight her directly.
And... fighting her directly will be very short work, as she'll just get angry and charge at Saki. When she's up close, one more sword strike will finish her off.
This causes her to plummet, but then...
----------
For Stage 1-3, suddenly... the entire surrounding city was cover in a sea of blood or blood-like substance, and Saki was caught in it. However, this seems to be something that Achi herself planned for him...
Kachua had survived her fall, and transformed into a massive titan. Not only that, but through Achi's blood, Saki, too, had also transformed into a similar beast! Are they hybrid Ruffians?!
----
Right now, in this form with Saki, the controls are mostly the same, except instead of rolling, you do a flash step to dodge, instead.
Use titan form to defeat Kachua one more time and complete the entirety of Stage 1.
Yes... This ALL happened in what the game considered the first real stage! OUT OF 3!
Saki remained transformed. He could no longer communicate with Airan nor Achi, but Achi knew that he'll eventually be restored back to his human form.
For now, with Saki like this, and all of the rest of the Saviors killed off, all the two girls cold do now is move forward with their mission to defeat the Volunteers and the Ruffians.
